surface pressure isotherms for punicine derivatives and oleic acid/sodium oleate

Pfeufer, Rike Alena

Data sets of surface pressure isotherms for punicine derivatives (octyl-, nonyl-, decyl-, undecyl- and heptadecyl-punicine) and oleic acid/sodium oleate.

Measurements were carried out at the Langmuir-Blodgett Minitrough of KSV Instruments Ltd. For each measurement the surfactant was solubilized in 1:1 EtOH and chloroform. This solution was placed on top of water (conductivity < 0.8 µS) and after an evaporation time of 10 min measurements were started.

data files are named as follows: LB_type of surfactant tabs in data files are named as follows: type of surfactant_ pH of measurement_date of measurement_number of measurement surfactants: OA Oleic acid NaOL Sodium oleate OP Octyl punicine NP Nonyl punicine DP Decyl punicine UDP Undecyl punicine HDP Heptadecyl punicine
